SPECIFICATION forming part 0f Letters Patent No. 670,153, dated March19, 1901.

Application tiled March 29, 1900. Serial 110.10.585. (No model.)

T0 all whom t may concern:

Beit known that I, CHARLES GARVER, a citizen of the United States,residing at Fort iVayne, in the county of Allen and State ofIndiana,have invented certain new and useful Improvements inSteam-Compressors; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in devices for utilizingexhaust-steam; and the object of my improvement is to afford means forcompressing exhaust-steam and returning' the same into the generator.

The device consists of the construction illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation, partly in section andwith one of the side plates removed; and Fig. 2 is a vertical centralsection on a line at right angles to Fig. 1.

Similar numerals of reference indicate corresponding part-s in bothviews.

1 is the casing, which is circular in form and is mounted upon or castintegral with the base 2. The sides of said casing are faced so as tosnugly tit with the side plates 8 8, which are secured thereto by meansof bolts or otherwise. The inlet-port 3 enters said casing near the top,beneath which the inner surface of said casing conforms for a shortdistance with the contour of the wheel 14.

The driving-shaft 12 is mounted in suitable bearings in the side plates8 8 and with one end extending to form a mount for the driving-gear 13.The wheel 14 is rigidly fixed upon the shaft 12 and ranges between theside plates 8, with one part of its outer surface snugly fitting againstthat portion of the casing 1 which conforms with the contour of saidwheel mentioned hereinbefore. Annular recesses 11 11 are made in thesides of said wheel, which serve as seats for the packing-rings 10 10.The side plates 8 8 overhang said rings and fit snugly against thelateral sides of said wheel.

Blades 7 7, dto., are arranged at regular intervals within suitablepockets 6 6, which are cast integral with said wheel. The said bladesextend radially outward from their respective pockets and are adapted toreciprocate therein. The springs 17, arranged in said pockets, areadapted to hold said blades outward against the inner surface of thecasing 1.

The thickness of the rim of the wheel 14 gradually decreases from theports 19, respectively, toward the forward blades 7 to allow spacesbetween said rim and the casing 1 for such condensation as may collecttherein.

Upon the inner side of the rim of the wheel 14 are arranged at regularintervals a number of laterally-movable Valves 9 9, having openings 2020, which register with corresponding ports 19 19, eXtending through therim of the wheel. The said valves are adapted to close said ports whenactuated as hereinafter described. Lugs 18 are cast integral with therim of said wheel and overhang the bevel sides of said valves and formways in which the same is adapted to slide.

Cams 5 5 are respectively secured to the inner sides of the side plates8 8 at points upon opposite sides of the shaft 12. The said cams projectfrom said side plates and engage the ends of said valves. As the wheel14 moves in the direction indicated by the arrow the valves aresuccessively engaged by the earn 5 and are thereby shifted laterally,thus closing the ports 19. The action just described takes place whenthe respective valves reach the point where the rim ofthe wheel 14 restsagainst the casing 1. The valves are successively reopened as they comeinto contact with the cam on the opposite side plate 8, which cam islocated at a point diametrically opposite the formerly-mentioned cam.Thus (referring to Fig. 1) the valves are closed when they reach theright-hand extreme and are opened when they reach the left-hand eX-treme by coming into contact with the cams alternately.

The blades 7 7 slide against the casing 1 and range in their respectivepockets according to the relative space between the wheel14 and saidcasing.

The discharge-port 4 passes through the side plate 8 at a point rangingwithin the rim of the wheel 14.

IOO

In use the machine is mounted upon a suitable foundation, and the gear13 is connected with an engi ne,so as to revolve approximately at aratio of one to three. The exhaust of said engine is led into thein1et-port 3,and the discharge-port 4 is connected with the generatorwhich supplies said engine with steam. As the engine revolves, the Wheel14 is driven, and the exhaust-steam from the engine passes through theport 8 info the spaces between the blades 7 7. The valves 9 admit thesteam between the blades to pass through the ports 2O and into the innerpart of the wheel 14 as the space between the casingl and said Wheeldecreases. At this juncture the valves 9 are closed by means of the cam5, which prevents the steam from retracting. The steam thus forced intothe central portion of the Wheel passes in a compressed form through thedischarge-port 4 and into the generator with which it is connected..

Having described my invention, what Il against the face of said wheel;and the side plates, secured to said easing and having extending oamsarranged respectively to alternately close and open said valves,substantially as shown and described.

In testimony whereof I aix my signature in presence of two Witnesses.

CHARLES GARVER.
